Water usage is probably my biggest. Living in a high desert, my wife and MIL see no problem with filling one side of the sink with hot soapy water to wash a few dishes because “that’s just how I’ve always done it”, to watering the grass and plants for hours. All of this makes me mental.
I won’t rape, torture, and murder vulnerable individuals. Call me radical but if I can be happy, healthy, and enjoy life without doing those things to animals, I’m not going to fucking do those things to animals.
